Hi guys I need some advise on an after market ECU, I need to change my ECU as my current Mines one cannot be mapped by any UK tuners, what I wanted to know what you guys advise as a good upgrade? Most GTR seams to be running a Apexi Power FC or a HKS F-con Pro. Are there different types (models) of these ECU’s ? I want to be running approximately 600 BHP in the future with 2860 -5 in mind. what is a used Apexi Power FC (with out hand held controller) worth? as I am in the position of obtaining one.
